Heidi Klum is in on the joke. During an appearance on "The Ellen DeGeneres Show" on Nov. 6, the German supermodel, 39, admitted she finally caved and saw Whitney Houston and Kevin Costner's 1993 movie "The Bodyguard" after she began dating her former bodyguard, Martin Kirsten.

Klum had to postpone her annual Halloween party in New York this year in the aftermath of Hurricane Sandy. "I was in New York," she recalled. "So many people have lost their homes and other people have lost a family member. I didn't think it was right to dress up and drink and dance. And so I rescheduled it."

The bubbly blonde's four children -- Leni, 8, Henry, 7, Johan, 5, and Lou, 3 -- "are very good," Klum said. "Obviously they don't hear a lot of the news and everything, so they just celebrated Halloween obviously here in L.A. It was also very different and they went trick-or-treating with their outfits on and love it. They're happy."

Klum announced her separation from Seal in January after seven years of marriage. She filed divorce papers in April.
